How do you handle this? Symptoms, but (still) a negative test.

My question might seem a bit premature, but it felt like a good idea to vent my heart here for a bit. I’m currently in a state of tension and waiting, because my early pregnancy test (so far) hasn’t come back positive.

My situation regarding trying to conceive?
I use the Ladycomp myself, so I know exactly when my ovulation is (red blinking light). I’ve been off hormonal contraception for 2.5 years now. I know my body well and have regular periods (within a 1-day difference). I ovulated on October 30th. The week before, we had unprotected sex at least 5 times (every other day). On the 30th, we did it twice. So it’s possible I got pregnant, even though this is the first time we’re trying.

Why did I take a test so early?
It’s October 7th now, which is only 8 days after my ovulation, but I could have been fertilized a few days before that too. Three days after ovulation, I was still completely calm about it. But on the fourth morning, I saw some brown mucus on my toilet paper. Implantation bleeding? The following days, I had some brown drops during some toilet visits, and a few days later, some blood in my underwear. Not much, but it was there. Today, I even saw a very small clot. But just now, I went to the toilet again, and there was nothing. This was accompanied by some dull abdominal pain, but that’s gone now. The drops of blood/brown remain.

My breasts have been extremely tight and painful for 5 days, including my nipples. Normally, they only hurt a bit on the sides before my period starts. Not more than a week before.

Last weekend I was very nauseous, but today that’s a bit less, though I do burp a lot (TMI). I also have a clearer feeling of hunger and my stomach is gurgling.

Also, I have to pee much more often. I consciously drink enough because it’s healthy and important for a potential baby, but now I have to go to the toilet after every cup of tea, even though I’m not someone who usually urinates that often. I’m also very thirsty and have a dry mouth.

My Ladycomp says I should get my period in 3-4 days, on day 29-30, as usual. Because my husband and I were a bit enthusiastic and impatient, and found the symptoms quite strange, we took a test (Etos Early). It was negative. A second test (Clear Blue Digital) was also negative. I probably tested too early.
I’m starting to doubt what’s going on with my body and still feel like I’m definitely pregnant because of these symptoms. The tests disappointed me and confused me. So I won’t do it again until my missed period.

What does the GP say?
The GP told me it could be implantation bleeding, even if it lasts 5-6 days. An very early miscarriage would involve more bleeding, because everything would have to come out. Of course, she advises me to wait until I should get my period, and preferably test a day after that. Or I should wait until I actually get my period, meaning I’m not pregnant. Then we’ll know for sure.

So what’s going on with my body?
I’ve had regular and clear periods my whole life. I usually get a lot of PMS symptoms, but I’m not noticing any of that now, even though my period should be coming next week. I’ve never had spotting before, and I’ve been off the Nuvaring for over two years. This is very strange for me. I find it quite annoying that my body is messing with me like this, right as we’re trying for the first time. That would be too coincidental, wouldn’t it?

My question?
Does anyone recognize this? I don’t need an answer or to know if I’m pregnant, and I know I can really only test after my missed period, but I’m just shaken and confused by my strange-feeling body. What’s going on, I keep wondering? And how do you hold out during the wait if you’re a bit of a worrier? How do you experience the wait when you do have symptoms? I don’t need a solution, just a bit of experience from someone here or a reassuring answer that helps me put things in perspective and hold on for a few more days.
