Hi I'm 23 yrs old and I already have 2 yr old who will be 3 in nov. In June 2015 I found out I was about 2 or 3 wks pregnant on 29th to the July 3rd I bleed went to the er and told me I was having a miscarriage on July 22 I started the depo shot dr did blood work to make sure my hcg levels where below 5 and they where, we'll July 6 all the way to July 21st I had unprotected sex and the 22nd the day I got my depo for the first time I had unprotected sex again which it had been about 3 weeks since my miscarriag. I Was having light bleeding for about 2 days before I got the shot but they told me it was my period, on August 13th I was having really bad stomach pain there more like pains when you get hungry it started about 2 am and last thought the day I tried eating and nothing the pain was ridiculous to the point it was making me vomit and had to leave work early, as of August 14th I was bleeding really light to the point where I didn't have to wear nothing so thinking it's my period august 15th i ended up fainting do to being out in the heat and not eating and being dehyrated (which i havent done that since i was 16 weeks pregnant with my son) today august 18th the bleeding has gotten heavier now. I feel so exhausted and weak and have a crazy appetite. My question is is there any chance that I can be pregnant but when dr did blood work to conform my miscarriag it was just to early to show that I was pregnant again it's been 5 weeks since I started my birth control and 7 weeks since I had miscarriage?
