I have been on injectable gonadotropins for two cycles with a trigger HCG injection advised when I have follicles large enough. I am now 11 weeks pregnant, and while I should be absolutely delighted I am now petrified it may not be my husband's baby. In the morning of Wednesday, July 16, my infertility nurse informed me that I had two follicles 16mm. and to take the HCG injection on Friday 18th in the morning, with timed intercourse for two days after this. I had intercourse with my husband on Saturday several times, and on Sunday and Monday. Unfortunately I made a huge mistake and had sex with another man on Thursday 17th July at 9 p.m. prior to the HCG injection. Up until now I thought that I could not be pregnant by this sperm. Then someone told me that this sperm could have persisted long enough to coincide with ovulation (which I'm told is 36 hours after injection). What I need to know is what the chances are that this baby is my husband's rather than this other man's? Please help me. I am so desperate.
It's a little too close to say it can't be the other man's, although the odds are in favor of your husband--so that's good. But whatever happens, please know that you've gone to a great deal of trouble and expense to get pregnant--it's a wanted baby. Follow through with your maternal instinct for wanting to be pregnant anyway. I know my vagueness doesn't help--and I wish I could tell you what you want to hear--but you've already figured it out yourself; the timing's been too tight here. No matter what, remember why you wanted to be pregnant in the first place.
