Im 29 years old and for as long as I can remember I’ve had 19-21 days in between my cycles. They’re 5 days long, and usually 25-26 day cycles. Well my last one was Dec 5-9. I had unprotected sex on the 9th and two times after that week - used pull out method. We also had sex multiple times in December after that but with condoms. So I’m thinking something could’ve happened on the 9th or those other times. My period would’ve came on the 30th, but it didn’t. I’m 11 days late now. I took 2 pregnancy tests 2 days ago when I was a week late and they were negative. I made an appt with my doctor that’s two and a half weeks out (cus they’re so booked). I’m just really worried because I’m either pregnant which is honestly okay - or I’m not and something terrible may be wrong with me. But the tests showed negative? Planning to test again this coming week when it’s been 2 weeks late if it is. The last week I had been so nauseous i was taking prescribed zofran but thought it was stomach problems because i had pizza that made me vomit and feel like i had food poisoning but I’m fine now. Anyone test negative the first week then positive or?
