My husband got back in town on December 8th, we immediately started having sex, we are a young couple so we have sex at least 3-4 times a day every single day, my menstrual comes every 31 days, it starts off heavy and when it ends its really light and it usually last 6-7 days. This month my menstrual was due December 13th, it came on December 12th immediately after my husband and I had sex and it was totally gone by December 14th. On December 14th we started having sex again, never with a condom always unprotected and he ejaculates inside of me every time. We had sex everyday from the 14th to the 19th and he left for work again. I am 25 years old, I have been pregnant 3 times and I have 2 kids already, my youngest is only 1 years old and I found out I was pregnant with my son I was only 3 weeks prengnat, after I had my son I had an IUD but it slipped out 4-5 months after I had it inserted. Its only been about 2 weeks so far and I already have a truck load of pregnancy symptoms: Frequent urination, sleeping a lot, feeling really hot or sometimes cold, clear liquid coming out of my nipples when I squeeze them, stomach growls a lot and always feels empty, pain on my lower left side of my stomach, cramps that come and go, headaches and definately mood swings, nipples look a little darker but i never really paid attention,havent really been that hungry though, I have been losing an awful lot of weight pregnancy test come out negative though...what could it be??
