Newly TTC help/advice

Jaime
Ok, I'm seriously so confused. So I got off my birth control (Nexplanon) on 4/26. I took like one week of birth control pills following nexplanon removal and stopped. 4/22-4/28 I had my period. 5/6-5/11 (today) I bled again.. really heavy the first 2-3 days then completely normal since, and now I'm done. Was thinking it might be a withdrawal bleed, but it could have been a normal period? Anyways, Glow is confusing the crap out of me. I was on BC (switching between some since 14) and had my nexplanon for 2 years. So I have no idea of what my periods were like before BC. I have no idea when I'm fertile or expecting to have a period. But I'm gaining weight and my boobs have blown up and I just don't feel normal. We had sex on a supposed super fertile day but when should I take a pregnancy test?! WHAT IS EVEN GOING ON?! SOMEONE HELP ME LOL 😂😂😭😭
