I'm a very fit and healthy 23 year old girl I work out 3 times a week and eat healthy nothing has changed and I'm not stressed or anything. My periods are always on point every month!! On February during my fertile week I had unprotected sex with my boyfriend he came in me and I'm not on any birth control and I didn't take plan b. I have missed 2 periods and I took a pregnancy test when my period was 10 days late but it was negative but the red line was a dark red I'm now 35 days late. I went to my docs Friday and he said come back in 2 weeks if my period doesn't come. Does anyone think I could be pregnant!!
