I had a c-section on 14th September (just over 10 weeks ago) hospital advised not to get pregnant for 2 years, I went on the pill and my partner used a condom (but it was too tight, was regular size and it’s what hospital gave me before I went home) I took the pill everyday at the same time like advised by my doctor, went for my 6-8 weeks post birth check at my doctors and blood results came back as positive for pregnancy so I took a few home pregnancy tests they are all positive, I’ve now stopped taking the pill, can I please have some advice this will be my pot of gold baby my baby born via c-section is my rainbow baby I also have a 19 month old son who is also my rainbow baby, I didn’t want anymore pregnancy’s that’s why I went on the pill, I’m 21 years old almost 22 I’m so scared about the risks, are they any risks? I also had SPD during my last pregnancy and that hasn’t gone away yet... I don’t want another baby what do I do? I really need some advice please would be much appreciated!
