So here's what went down. I had sex 4 weeks ago. He came in me and lied and said he can't have babies. Well after about 3 days, I felt like I had a bad yeast infection. I went to the free clinic but they could not do anything for me. And by that day that u went to the clinic my "yeast infection" had gone away and I got my period like 3 days after. Well I finished my period and its been... Gosh I do t know how many days but I sometimes feel cramps. Sometimes it's on my left side and sometimes on my right and even middle area. Also: my vagina seems to have changed shape completely. It looks like my hymen is swollen and I can see inside more and it looks lumpy. I have no pain now and I am not usually sexually active like I was over 6 months ago. I feel like my "yeast infection" was first noticed a little while before I had sex. I am pretty worried about the pregnancy scare. I haven't had cramps after like this before. I also feel my stomach a little upset for the first time. And it's before bed. Please help me I'm so desperate. I live with just my dad an he gets so disappointed at me. I'm so scared anything helps. Thank you.
