Me and my boyfriend had sex about a week ago, last Friday (09/19) and my usual period comes around the 26-02 or 15-19 It is irregular, we had intercourse again but there wasn't any ejaculation on (09/29) I understood my period was late but I've never actually had a constant period date. I was late 8 days before getting my period it started off light but came to be heavy as it usually is supposed to be. We have decided to have a home pregnancy test just in case because I heard you can still have your period while being pregnant so we just wanna be sure. This isn't the first time, we were pregnant two years ago but I had a miscarriage at 10-11 weeks. I had all the symptoms last time but I have constant headaches, irribility, constant feeling of needing to urinate but end up not having to, very emotional, back pain... were very concerned... and i need advice if this is something usual for pregnancy or not. I am 16 and he is 17, Thank you for your time.
