Hi ladies so I need a bit of advice, I had my baby 6 weeks ago. At around week 4 I had unprotected sex with my partner (things got a bit heated after a long time without lol) the past couple of days I've been feeling really sicky, tired and occasional stomach cramps. I've just finished my first period since having him which lasted roughly a week I wasn't bleeding when we had sex. I know there's high chance of falling pregnant but when would I do a test? As I'm not sure if my HGC levels would be down by now and also because I've just finished a period it'll be next month till I know if I've missed one? Please help lol panicking !
