Maybe pregnant after all?

15:43 NHah Hello, maybe a silly question and I have no idea if I'm in the right place here. My partner and I have been trying to get pregnant for almost a year now. Lately I've had very irregular cycles, impossible to predict. Always between 35 and 55 days. Although the last 3 months it was a 35-day cycle. So I thought I should get my period again on April 7th. It didn't happen, could it still be? But a week later I had bleeding. That was last Friday. Normally I'm usually on for a solid week. This time it was already over on Monday. Although it felt like a normal bleed to me, I didn't have the lower back pain etc that I normally have. Since Thursday I've had the feeling that my belly is bloated, and it's also sensitive when I press on it. Unpleasant feeling. Since today this is also pulling slightly into my lower back. I know it's almost impossible since I've had my "period", but could it be that despite the bleeding I could still be pregnant? I did have this feeling before I got my period. But well, because I got my period, I pushed it aside. Now I'm having this feeling again, what is this? Also my belly is literally swollen. I expect it's not like that, but there's something inside me that makes me want to ask you guys, maybe one of you has experienced the same or something similar? Thanks in advance!
